"misleading", lol. A bit reaching there since pretty sure no mentions of Knowles was ever made. They mostly outsource to Bellsing or maybe even the various BA makers (not hard to find such companies, like Estron or Binary)
Hisenior sells the B5+ (5BA) for around 100 bux and they claim its Knowles BA. Plausible that its either some Knowles BA or lower-end models, since most Hisenior products have gained quite favorable impression. Depending on how the AS10 pans out, the B5+ seems a natural upgrade to it (nearly double the price, but its quite pretty)
I have ordered the B5+ and just waiting for it to arrive. It would be a good comparison to compare it to the AS10 and the BS10 when it eventually gets released.
